用非完全熔合碎裂模型来分析600MeV/u Au+Au 反应中弹剩余核的多重碎裂现象.理论计算得到的弹剩余核质量数、激发能及热力学温度与实验数据基本一致,很好地解释了 Au+Au 反应中热力学温度随每核子激发能变化而出现的回弯现象,使衰变模式相变和液气相变统一起来.
The incomplete fragmentation model was used to analyze the multifragmentation phenomenon of the remaining nuclei in the 600MeV / Au Au Au reaction.The theoretically calculated mass, excitation energy and thermodynamic temperature of the remaining charge of the projectile were basically consistent with the experimental data, and well The phenomenon of the bend of the thermodynamic temperature with the change of the excitation energy of each nucleus in the Au + Au reaction is explained. The decay mode and the liquid-gas phase change are unified.
